Projects on my new, to me. 1974 914-6 Options

[jerhofer]

I'm sure it was a hit. It looks very "finished". Most electric cars don't. Congrats to both of you. I hope we can meet up next time I'm in Charlotte.

It is a very finished car down to having AC. He used a 380V Tesla AC compressor that is mounted in the smuggler's hole in the front trunk. AC is almost a necessity in this part of the world, especially the past few days. It has good headlights, good brakes, and he had all of the stock 911 gauges re-programmed to work with the electric motor. The temp gauge shows the motor temp, the fuel tank gauge shows remaining charge, etc. He lives about 50 miles from the show site which was the longest drive for he car to date.

The body shop guy had the car this week to do a final polish on the paint, to have 3M invisible bra installed and the windows tinted. Matt picked the car up Friday and left his 700hp 1979 El Camino at the shop. Yesterday, he and his 18 year old son Garrett went to pick up the El Camino in the 911. On the way back, he let his son drive the Porsche. When they came up to a stop light, Garrett slotted the 911 into the opposite lane, and looked over at his dad with this huge grin on his face. Matt tried valiantly with the El Camino, but the 911 left the him in the dust.

And the saga continues. Last week I visited John and found that nothing had been done on the engine. More excuses. Today I performed an intervention and brought everything home!! I hooked up my utility trailer to my Audi Allroad to haul the engine and transmission. Everything else went inside in various tubs. A call to AAA soon had a roll-back there to take the car to my house. The car had been at John's for five months!!!

Once I decided that I wanted to do this I began thinking about where I was going to take the motor. Because of the fuel injection I wanted someone working on it who understands that system. The obvious choice would have been Richard Clewett but California is a long way from North Carolina.

Then I remembered talking with my 40 year plus buddy about his PCA race car while we were in Florida this past winter. He has basically this identical motor in his car with Richard's injection system. And it was built by a 30 plus year friend in Elkhart, Indiana. I called my friend with the race car to see if my other friend was still building motors. Turns out he had just rebuilt the race car motor this past spring. And I also discovered that my engine builder friend had built another engine with this configuration for another friend of mine.

So I called my engine builder friend. After some get acquainted talk, we got down to business. At one time he was the lead technician at the local Porsche dealership. That job was followed by him owning an independent Porsche repair shop. When I lived in Indiana, he used to come over to help me on projects and taught me much of what I know. In 1989, he built a 944 motor at my house that I ran in a track car for five years, followed by my son having that car for another four years. Never had a bit of trouble with that motor.

His path to working on cars began with the vocational school he attended while in high school. That vocational school had asked him for some advice and he ended up volunteering there while had he his independent business. One day the school asked if he would be interested in becoming an instructor. He wasn't making all that much money with his shop and the new job came with great benefits. He has been there for fourteen years now...and loves it.

He was more than willing to build the motor. And then he asked if I would be OK with him using the motor in his classroom. He has eight seniors this year who would be thrilled to work on a Porsche motor. My friend would be overseeing them to make sure everything was correct. I agreed. He is very excited about his kids working on the motor as it isn't likely they would be working on this type of motor in their future careers. They normally build a small block Chevy so this would be quite different.

I am taking the car and motor to him next Monday. We are leaving on a nearly two month motorhome trip just before Labor Day so they can work on it while I am gone. This won't be a quick turnaround but the motor will be with someone that I trust. While he is working on the motor, my other friend will be storing the car in one of his buildings. I just may get this thing back together!

My boat guy who was going to apply new gelcoat to the fan shroud also did not work out. John owes me some money and, as partial payment, he gave me a fan shroud. I drilled out the rivets and painted the shroud and the metal part separately.

The carburetor hats had a few scratches before I took it to John. There were a few more when I got them back. Nothing terrible but enough that I blasted them and took them ot my powder coater yesterday. I picked them up today with a cost of $20.

The fins on the alternator housing were rusty. After doing some sanding, I painted them with a high temp paint.

(IMG:http://www.914world.com/bbs2/uploads_offsite/i188.photobucket.com-22140-1565206412.3.jpg)


I did an inventory yesterday and found that the only part that was missing was the band that retains the fan. I drove over to John's this morning and got it. Now that it was apart, I blasted it and painted it gold.

Now all I have to do is pack everything to prepare it for transporting in the truck next Monday.

Hope it works out for you, at least you pulled the trigger and got your stuff back.

BTW, who's cabinets did you use for your workbench.

Those cabinets are from Harbor Freight. They have held up well. They have these on sale from time to time.

I am sure your new path will work well. Marty will do a great job!

Isn't it amazing how many miles this car has traveled without even being assembled.

Let me know when you plan to go for a test drive and maybe I can stop by and catch a quick ride to celebrate.

All the Best,
Ed

I have an update. As a refresher, the engine came out of a Euro Carrera and began as a 3.0 liter. Marty told me to order a SC basic rebuild kit with standard bearings. I also ordered ARP studs and rod bolts. When Marty began to assemble the bottom end, he discovered the bearings were too small. This is the bearing that came in the kit.

(IMG:http://www.914world.com/bbs2/uploads_offsite/i188.photobucket.com-22140-1575989359.1.jpg)

This is the bearing that was in the motor.


(IMG:http://www.914world.com/bbs2/uploads_offsite/i188.photobucket.com-22140-1575989359.2.jpg)


(IMG:http://www.914world.com/bbs2/uploads_offsite/i188.photobucket.com-22140-1575989360.3.jpg)

I bought the kit from Vertex. After getting together with Vertex's owner, he and Marty came to the conclusion that the engine, while a 3.0 liter, had 2.7 rods. Marty knew there were some differences between the Euro Carrera motor and a SC motor, but did not know about the rod issue. The Euro 3.0 has the aluminum case rather than the magnesium case of the 2.7. Marty now has the correct bearings.

When Marty inspected the pistons, he discovered one had bolt thread marks on the top of the piston where a bolt had been squeezed between the piston and the head. I did read where the guy who built the motor dropped a bolt into the engine and had to disassemble the part of the motor to get to it. Evidently the engine was hand cranked before the bolt was removed. Marty also noticed that it appeared the cylinders had been honed. He is concerned that the Nikasil lining had been compromised.

The pistons and cylinders were sent to EBS. This is their assessment.

"Just a quick note to let you know that we have received your pistons and cylinders. The JE pistons are very old. No job number stamped on the inside of the piston. Without the job number it's impossible to know exactly what they are. JE has significantly improved their 911 air cooled pistons and ring pack since then. I would recommend going with a new set of JE pistons 98mm 9.5:1CR. They will be correct for the application, a slight bump in compression ratio for a bit more performance, coated piston skirts and lightweight wrist pins. Cylinders have had something done to them. I would recommend plating the cylinders to make sure that everything is 100% correct. They might be within spec but I do not know what process they used to hone the cylinders. We can have them inspected and measured, cost is $100/set. Attached is a copy of your quote. Let me know if you have any questions. If you would like us to measure and inspect the cylinders allow 7-10 days."

I will be calling EBS later today to give them some money. And that is where I am at to this date.

Never give up.

Pretty sure those were 9.5 / 1 pistons. Funny thing is I'm pretty sure the pistons and the cylinder work was done by/through EBS, but that was all arranged by the customer. Unfortunately I don't have any records for that build.

[sixnotfour]

early euro 3.0 used 2.7 crank and rods,,,Very desirable engine case for the guys who want to build short stroke engines , 66mm crank..direect fit...6 bolt flywheel aposed to the usa 78- 8 bolt ,

I'm told the trick is to have good flywheel bolts and then over torque them so they stay tight.

[sixnotfour]

all cylinders can be honed , but each type reguires a different method, hone marks in the cylinders , in nycasil is good ok....EBS is great but as you see they outshop the work

I'm pretty sure they send it to US Chrome.

I've always wondered if it was US Chrome or Millennium Tech. Interesting.

When John had the car, he supposedly checked the cam timing and said it was correct.

I had a message from the engine builder that the main bearings were also different from a SC motor. The incorrect ones have been exchanged.

Yes,,, just 180 out....main bearings,, yes ,,early rare 3.0 case...

Covid-19 update.

At least for now, the school where my friend works is having students back in class next week. The heads have been sent out to be redone. Once everything is back, the plan is to finish up the engine build. As part of their training, the class will install the motor and tranny. They now have a dyno at the school. Once it is back in the car and running , my friend will tune the car on the dyno.

As we all know with this pandemic, nothing is certain. If they have issues and transition to online learning, my friend will finish the build on the motor. I will probably head up there to help him install the drivetrain and we will put it on the dyno to tune it.

@jerhofer any updates?
